Definitions

  • the present invention relates to a method for wet-drafting an assembly of staple fibres, the application of this method to manufacture twistless or substantially twistless yarn, the drafting means to apply this method, and the staple fibres or yarn whenever manufactured by the application of this method.
  • Both slivers and rovings can be subjected to wet-drafting.
  • the fineness of the drafted fibre assembly and the yarn obtained therefrom will depend on the thickness of the material supplied.
  • a maximum drafting factor of about 100 only can be attained.
  • the wet-drafting should be performed in a continuous process comprising at least two coupled drafting zones, the staple fibres entering the first zone directly after wetting, while the two zones together produce at least a 100-fold elongation.
  • this method of wet-drafting can be applied to the manufacture of all sorts of yarns, this method lends itself particularly well for the manufacture of twistless or substantially twistless yarn from a sliver which contains at least two staple fibre components, of which at least one is a potential adhesive providing for the bonding of the staple fibres, while the sliver is drafted in a wet condition to a thinner fibre strand, whereupon the yarn is obtained through bonding of this strand.
  • a two-cylinder drafting system i.e. a drafting system with only one drafting zone, appears to give a too small a drafting factor, as already stated. Also a four-cylinder drafting system in practice presents difficulties in the manufacture of twistless or substantially twistless yarn.
  • FIGURE illustrates an embodiment of a three-cylinder drafting means suitable for the method according to the invention.
  • the cylinder pairs of the three-cylinder drafting means are indicated by 1, 2 and 3.
  • Each of the pairs comprises a rubber roller 4, 5 and 6 respectively, and a serrated roller 7, 8 and 9, respectively.
  • a condenser (10 and 11 respectively) is provided at the feed-in side of cylinder pairs 1 and 2 .
  • a belt 13 is passed around roller 5 and a wheel 12, the belt running at a given angle to the feedthrough direction of the fibre strand being drafted.
  • a guide 14 is situated between cylinder pairs 2 and 3 at the side of the jointing surface between the lines of contact of the cylinder pairs.
  • the drafting means comprises a unit 15 to blow air along the roller 8.
  • a sliver 16 is used, which is wetted by passing it through a liquid bath 17.
  • the sliver to be passed through this bath should cover such a path that it can absorb sufficient liquid. This path depends, among others, upon the feedthrough rate.
  • the time required therefore can be set by making the length of the path in bath 17 variable, as shown by the dotted lines in the accompanying FIGURE.
  • an excessive amount of liquid is absorbed between the fibres by the sliver. The time selected depends on the choice of the staple fibres being used and the thickness of the fibres.
  • the sliver 18 drawn out of bath 17 is fed to the three-cylinder drafting means via condenser 10 of cylinder pair 1.
  • the function of condenser 10 is to coarsely control the excessive amount of liquid between the fibres, while also an assembly of these fibres is realised.
  • the fine control of the amount of liquid can be realised at the feedthrough between rollers 4 and 7, for example by correctly setting the pressure exerted between these rollers, by the shape of the serration of roller 7, by the choice of the hardness of the rubber roller 4 etc.
  • a smaller pressure variation between rollers 4 and 7 can be used to control the required liquid contents, taking into account the minimum clamping pressure between the rollers, as required for the drafting.
  • a sliver comprising at least two staple fibre components, of which at least one component is a potential adhesive providing for the bonding of the staple fibres may be false-twisted and bonded after the passage through the system here described.
  • a condenser may also be required at the feed-in side of cylinder pair 3.
  • the method here described may be applied to single staple fibres and to staple fibres comprising several components, as well as to an assembly of fibres consisting of melting fibres or of swellable, gelatinisable or soluble fibres.
